KVM virtualization storage pool Configuration

1. Define the storage pool directory

[[Email protected] kvmimg] # virsh pool-define-as vmdisk -- type dir -- target/data/kvmimg/pool vmdisk defined2. create a defined storage pool [[email protected] kvmimg] # virsh pool-build vmdiskpool vmdisk built

3. view the defined storage pool. The storage pool cannot be used if it is not activated.

[[Email protected] kvmimg] # virsh pool-list -- all # view all storage pool names autostart defaults active Yes vmdisk inactive no [[email protected] kvmimg] # [email protected] kvmimg] # virsh pool-Info vmdisk # view vmdisk storage pool information Name: vmdiskuuid: 6e80ce65-c13c-aac2-02fe-c370b64631_state: inactivepersistent: yesautostart: No

4. Activate and automatically start the defined storage pool

[[email protected] kvmimg]# virsh pool-autostart vmdiskPool vmdisk marked as autostarted[[email protected] kvmimg]# virsh pool-start vmdiskPool vmdisk started[[email protected] kvmimg]# virsh pool-info vmdisk     Name:           vmdiskUUID:           6e80ce65-c13c-aac2-02fe-c370b6463109State:          runningPersistent:     yesAutostart:      yesCapacity:       774.28 GiBAllocation:     55.51 GiBAvailable:      718.78 GiB[[email protected] kvmimg]# virsh pool-list --all      Name                 State      Autostart -----------------------------------------default              active     yes       vmdisk               active     yes

5. Create a qcow2 VM storage volume in the storage pool, and then you can directly use the qcow2 disk file to install the system.
